The state of Tennessee investigated an outbreak of Norovirus with another state in January, 2009. The strains of Norovirus from the sick people matched Norovirus found in unopened, raw oysters from Mississippi Area 2C. In a second investigation, eleven people became ill after eating raw oysters at a restaurant in Chattanooga, Tennessee on March 5 and 8. The ill persons were confirmed to have Norovirus. This investigation prompted the recall of Mississippi Area 2C oysters that were harvested on February 14 and closure of the harvest area.
